The change adds a DNSX test that verifies configured response-code filters and domain options retain their values.

Changes

DNSX option validation

Layer / File(s) Summary
Option preservation test
libs/dnsx/day3_w13_rcode_test.go
Adds TestOptionsResponseCodeFilterValidation. The test configures NOERROR,NXDOMAIN and one domain, then verifies both values are preserved.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to 0a2ca

The new DNSX test currently references fields absent from Options, so it will not compile, and it does not cover all stated response codes or verify the configured domain value. The PR is not merge-ready until these test issues are corrected.

either add ResponseCode and Domains to the Options declaration with the required
integration, or update the test to use the existing Options API. Ensure the
chosen approach preserves the test’s intended response-code and domain
configuration without introducing mismatched fields.

NXDOMAIN, and assert the domains slice equals []string{"test.example.com"}
rather than checking only its length.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win

Fix the Options field mismatch before merging.

The supplied Options declaration in libs/dnsx/dnsx.go:24-35 contains neither ResponseCode nor Domains. Lines 11-12 therefore produce undefined-field compile errors. Add these fields to Options, or update the test to use the existing API.

Cover all configured values in this test.

The objective includes NOERROR, SERVFAIL, and NXDOMAIN, but Line 11 omits SERVFAIL. Line 15 checks only the slice length, so it does not prove that test.example.com is preserved. Include SERVFAIL and compare opts.Domains with []string{"test.example.com"}.
